It might be, it's a long time since I visited the code, as far I was
aware it was working fine, but then not all engineers as as observant
and enquiring as yourself :-)

Any adjustment would be best done in Optimizer.  Would it be possible
you to provide me a simple model that reproduces the problem with the
Optimizer not assigning DataVariance?
